Last weekend a group of us hit the dyno and someone brought a 1M. With full exhaust and no tune it put down 330s HP and 370 TQ on a low reading dyno, matching all 3 M3s in HP and destroying them in TQ. I wouldn't be surprised if it's the same engine in the new M3 which would be disappointing in that we wouldn't see a new engine, but the 1M engine is nothing to cry about.

Just Sayin...

Folks, the article clearly states that the M3/M4 engine is the S55, not the N54 from the 1M / 335i.
